Open-E DSS V7 Active-Active iSCSI Failover Data Server (DSS1) node-a 9. Run Failback Function IP Address:192.168.0.220 After completing this step, the status for node-a resources should state "active on node-a (local node)" and the Synchronization status should state "synced". Then, you can apply the same actions for node-b resources. NOTE: The Active-Active option allows configuring resource pools on both nodes and makes it possible to run some active volumes on node-a and other active volumes on node-b. The Active-Active option is enabled with the TRIAL mode for 60 days or when purchasing the Active-Active Failover Feature Pack. The ActivePassive option allows configuring a resource pool only on one of the nodes. In such a case, all volumes are active on a single node only.
